To aZZ whom. may concern.-

Be it known that 1, JOHN G. KEITH, a citizen of the UnitedStates,residing at Chicago, in the county of Cook and State'of Illinois,have invented certain new and useful Improvements in Wheels; and I dohereby declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification. I

My invention relates particularly to vehicle wheels having hubs composedof pieces screwed to each other and separable from each other, whereby abroken part of the hub or broken spokes may be replaced withoutdifficulty. I

In the accompanying drawings: Figure 1 is a side elevation of a hubembodying my improvement, the spokes being cut ofi where they enter thehub. Fig. 2 is a central section parallel to the axle to which the wheelis applied. Fig. 3 is a section in line 33 of Fig. 2. Fig. 4is asectionin line 4-4. of Fig.

2. Fig. 5 is a section in line 5-5 of Fig.2.

Fig. 6 is a section showing a modification of the construction shown byFig. 5.

A is the axle of the vehicle. This is of any suitable form, but has,preferably, a cylindric portion entering the hub and having at the innerend of the hub an annular shoulder, A, and at the outer end the usualnut, A

B is the outer section of the hub, and G is the inner section of thehub.

D Dare the spokes.

The section, B, has a seat, B, for the ends of the spokes, D. .At theouter side of said seat a flange, B rises from the section, B, and restsalong the outer side of the spokes. Opposite each space between thespokes, an extension, B, of said flange extends-between the spokes.Between the inner ends of the spokes and the axle, the sections, B andO, telescope oveneach other and the meeting faces are screw threaded toeach other.

E is a sleeve surrounded and threaded to the section, 0, by threads ofless pitch than the threads by which the sections, B and G, are joined.Adjacent to the inner side of the series of spokes, D, said sleeve, E,has a flange,

Serial No. 503,538. (No model.)

E, perpendicular to the axle, A. Extensions, E extend from said flangeinto spaces between the spokes, D, similar to the extensions, B on theflange, B The ends of the spokes may be angular as shown in Fig. 5, orrounded as shown in Fig. 6, and the extensions, B and E may be shaped toadapt them to enter the spaces between the spokes of the particular formused. c

In putting the wheel together, the spokes, D, are put into position uponthe section, B,

of the hub. Then the section, 0, is turned partially through the sleeve,E, and then started into the section, B. On turning the section, 0,farther, it is run rapidly into the section, B, and slowly through thesleeve, E,

said sleeve being gradually drawn toward the spokes. The relation to orpitch of the threads between the sections, B and C, and between thesections, 0, and sleeve, E, is to be such as to cause the flange, E, tobe pressed tightly against the spokes by the time thesection, O,

is driven fully into the section, B. It Willbe seen that the sleeve, E,cannot rotate after the extensions, E enter the spaces between thespokes, D. Consequently the sleeve, E, may be turned back and forth uponthe section, 0, for adjustment until the distance the sections, 0, musttraverse to fully enter the section, B, is sufficientto'draw the sleeve,E, and the extensions, E intoposition with reference to the spokes, D,without again rotating the sleeve.

The sections, B and C, may be enlarged interiorly at each side ofthe'over-lappingrand threaded portions so as to form in said sectionsannular recesses, B, and O, respectively, for the reception ofanti-friction rollers, F, of proper size to bear against thesections andthe axle, A. The portions of said rollers toward the plane of the spokesmay also abut against said sections, while the opposite portions mayabut against washers, F, the inner washer resting against the shoulder,A, and the outer washer resting against the nut, A Said washers may beomitted and the rollers, F, allowed to bear directly against theshoulder, A, and the nut, A7

I claim as my invention- 1. .In a wheel, the combination with the ingextensions, B extending into the spaces between the spokes, a hubsection, 0, threaded to the section, B, a sleeve, E, threaded to thesection, 0, by threads differing in pitch from the threads joining thesections, B, and C, and having a flange, E, bearing extensions, Eextending into spaces between the spokes, substantially as described.

2. In a wheel, the combination with the spokes, of a hub section havingaseat, B, upon which the spokes rest, a flange, B having extensions, B,extending into the spaces be-' tween the spokes, a hub section, 0,threaded to the section, B, a sleeve, E, threaded to the section, 0, bythreads difiering in pitch from the threads joining the sections, B, andG, and having a flange, E, bearing extensions, E extending into spacesbetween the spokes, the sections, B, and 0, having annular recesses, 13,and 0 respectively, adapted to receive anti-friction rollers, F,substantially as described.

In testimony whereof I aifix my signature, in presence of two witnesses,this 28th day of February, in the year 1894.
